1992 Nissan 100NX from UK and Ireland - Comments

When bought the car had carb problems which caused it to intermittently misfire. Tried many Nissan main dealers who either told me it was the auto-choke (which I knew it wasn't) or that the carb needed replacing at £650.00 plus labour. The Nissan dealer in Wisbech (J.S. Holmes) knew exactly what was wrong when I explained the problem on the phone and then fixed it for £150.00. It now runs fantastically well and I haven't had a single problem with it since.

Overall for me a nice little car that performs OK, without setting the world on fire, but it's comfortable, quite economical and you can take the roof off. It's got quirky styling, but hey you see less of them about than Porsches so it's good to be different The main thing so far would have to be it's reliabilty. Apart form the carb problem it's been superb.

Nissan main dealers in the main are not even slightly interested in helping you out because of the age of the car, but there are one or two good ones out there, just hunt around or you'll end up with a seriously dented bank balance!

I would like to know exactly what was wrong with the carburettor (lean mixture or something like that?), because I`m tired of replacing this and that, and not really finding a permanent solution to the problems.

I bought a Sunny -92 with GA16DS engine one year ago/10 000 miles, and shortly thereafter the problems started. Seems to be oil-related, because the symptoms got worse (!?) immediately after each of the first two or three oil changes.

Then I started using Auto-Rx, which has reduced the symptoms, and the car runs really well for periods (will go through second and final rinse-phase this spring).

What about the EGR- and PCV-system, should I replace something, or just clean (thinking of carbon-build-up etc.)?

I tried to email the dealer in the review, but they have not replied. It would be nice if someone could just post the solution; then everyone could get on with fixing their cars.

I had this jerking problem on acceleration with my 100nx someone suggested changing the ht leads - no difference then what a suggestion I had - start using REDEX, Car now runs much much better.
